SPECIFICATION forming part of Letters Patent No. 408,693, dated August 13, 1889.

` Application led December 2l, 1887. Serial No. 258,606. (No model.)

To all whom, t may concern.-

Be it known that I, GEORGE IV. CANNON, a citizen of the United States, residing at Poughkeepsie, in the county of Dutchess'and State of New York, have invented a new and useful I-Iand Elevator or Hoist, of which the following is a specification'.

My Objectis to produce an elevator of simple construction and easy operation, so graduated as to raise easily and safely any weight,

heretofore obtained a patent, No. 361,263, for a dumb-waiter adapted to raise with facility like loads; but this invention is of different construction and operation. I secure greater power by introducing gear-wheels and so arranging myropes that my operating and hoist ropes supplement each other in holding the load in case of the breaking of either rope, and so long as either rope remains intact the By a brake-rope at the side I hold the load in any position.

My invention consists in my peculiar arrangement of hoist-,wheel axle, gear-wheels, weightwheel, pulleys,A hoist-rope, and endless power-rope to produce a motion varying from one to six to one to ten between the car and a point in the power-rope.

I will now describe my invention in reference to the drawings.

Figure l is a front View, slightly in perspective, exhibiting the operative parts in position. Fig. 2 is a plan view of the top ofthe A is the power-wheel; B, the large wheel. O, D, I-I, L, and G indicate small pulleys; A',

wheel B, and A", the ordinary standards of the small pulleys; F, t-he shaft; J, the small cog-Wheel attached to the shaft; E, the large cog-wheel; c, the groove-Wheel on the side of the large cog-wheel, over which the hoistrope passes.

K shows the top of the elevator, to which are screwed the standards supporting the operative parts.

I indicates the brake, which is operated against the power-rope by the cord T.

Q is the endless power-rope 4by which the elevator is operated.

R is the hoist-rope, one end of which is fastened to the top of the elevator-car at T, and it passes up over the large groove on the side of t-he large cog-wheel and under the small pulley S, over the pulley L, and down to the snatch-block holding the pulley M.

M is the pulley iny the snatch-block.

N is a Weight.

The endless power-rope Q passes up on one side of the elevator and down 011 the other, and may be operated by being pulled by the hand on either side.

The weight well or space for its ascent and descent may, by means of the pulleys, be placed on the rear or right or left side, as convenience of space may require in construction. The power-rope Q passes on the left side over the large wheel A, under the pulley C, over the pulley D, down through top K and under the pulley M, up through top K and over the pulleys II and G, down to and under the pulley O and up and over the large pulley B, and down on the right side of the elevator and around the bottom toits ascent on theleft side.

The wheel A, I prefer to make about ten times as large as the cog-wheel on its shaft J, and cogwheel E about three times as large as shaft J, and its grooved wheel e, attached to it, is about two-thirds the size ofwheel E. These latter wheels may be placed on standards, as shown, or journaled on t-he back legs of the standards A. .The guide-wheell B, I prefer to make about twelve to fifteen inches in diameter, and the other pulleys C, D, H, G, O, L, and S about six inches in diameter, and for all ordinary loads my y,powerwheel A about thirty inches in diameter. The size of A and the cog-wheels J, E, and e, and the weight of N may be changed to adaptthe elevator to different loads and powers. The cam-brake I is placed on theJ shelf or top K, and can easily be operated by hand applied to the cord T.

To operate my elevator, pull down on the left side of rope Q,Which tightens the rope R, lifts the cage, and the descending weight N takes up the slack in the endless rope .as the car is lifted, and in case the hoist-rope R should break at any time the weight coming on the operating-rope at O would cause the car to impinge in its grooves and stop the load from falling.

IOO

the hoist-wheel A, axle F,eog-wheels.l and E, Wheel e, eennterpoise-Weiglit N, pulleys M, L, B, C, D, H, G, and S, the hoist-rope R, and endless power-rope Q, :is Shown and described.
